I guarantee it will work, you just need an Oxy/Ac torch and a compressor

Heating up the area will work. Metal has memory.

So, after two freeze cycles (my wife dumped the water out of it yesterday before she put it back in while I was at work :banghead:  so that one didn't count. I guess she doesn't understand hydrogen bonding.) the dent looks the same. For this last cycle I used a propane torch to heat up the dented area to try and only melt the ice there. I have not looked at it since I put it in last night though. Hopefully that made a difference in it's effectiveness.

Me too!

 

I will be out of town for the weekend, so I won't be able to check it until Sunday night or Monday. I'll keep you guys posted on the progress though and I'll take some pics next time I look at it.

You must be using water from a KTM radiator or something, cause I've done this trick 6 or 7 times with success

I've done the freezing a few times and it works but it may take a few times to get the dent out.

 

Heating a pipe with a torch and putting 100 psi in it is a really bad idea.

It's working! The dent is almost all the way gone. This isn't a great pic but here it is. It's back in the freezer for another go.

Not going to happen. Most of that is baked on dirt that the pressure washer couldn't knock free, but trying to keep a steel header rust free is a loosing battle in the soggy Pacific Northwest.

Thought those headers were stainless steel.

They are, but high heat and always being wet and pelted with rocks will make even stainless rust slightly.
